How Do I Prevent Mice From Getting in the Attic?

At one point or another, homeowners may notice that mice have gotten into the attic space. In the winter, cold weather will naturally cause mice to seek warm areas, and here, the attic is ideal. Although mice (and other rodent animals) can infiltrate many parts of a house, the attic presents a very good habitat. With mice, one of the problems in an attic is that the space can easily get contaminated. But mice can also get destructive. They eat electrical wiring, fiberglass batts, even rigid foam insulation. And with more serious mice problems, selling a home may be problematic.

With mice, prevention is the key – it’s important to stop them from entering the attic entirely. And this is best achieved by sealing the attic space completely with something like spray foam insulation. It’s obviously a preventive measure, and will not do much if the mice have already inhabited. However, sealing with spray foam makes a world of difference. Every little crack and crevice is sealed, and no entry points remain. As well, mice are not attracted to spray foam - it doesn’t resemble a food source, and therefore isn’t something that they are interested in eating.

Bottom line, spray foam is a home insulation product. But by sealing a space so effectively, it also prevents mice from getting into the attic. Homeowners who install spray foam insulation in the attic will benefit most from improved home insulation, better-controlled moisture, and enhanced indoor comfort. However, the added benefit, of course, is an attic space that is effectively sealed, preventing mice from even entering, let along habituating. Spray foam insulation is an install that is best managed by an expert. An expert approach will ensure a quality job and optimium results.
